load_instrument_or_effect

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description must disclose behavioral traits. It only says 'load onto a track' but does not mention side effects (e.g., replacing existing devices), error states (invalid URI, missing track), or required permissions. This is insufficient for safe invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is fairly concise with two sentences, but the 'Parameters:' label is unnecessary. It is front-loaded with the main action, making it easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool loads an instrument/effect onto a track, the description omits critical context: whether the track must exist, what happens if it's already occupied, error handling for invalid URIs, and any side effects. With no annotations and few parameters, the description should provide more completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has no descriptions (0% coverage). The description adds meaning by explaining track_index as 'the index of the track' and uri with an example, but lacks details on URI format constraints or track_index bounds. It provides more than the schema alone but not fully compensating.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool loads an instrument or effect onto a track using a URI, specifying the verb and resource. It distinguishes from sibling tools like load_drum_kit by being general.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool vs alternatives like load_drum_kit, nor does it mention prerequisites or exclusions. This leaves the agent without context for appropriate usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
